Description
Technical field
The present invention relates to telecommunication system, especially but not exclusively relate to wireless cellular telecommunication network.
Background technology
Cellular telecommunication system covers or service area based on sub-district or similar radio.General packet radio service), standards such as TD/CDMA among AMPS (American Mobile Phone System) or DAMPS (digital AMPS) or WCDMA (Wideband Code Division Multiple Access (WCDMA)) and the UMTS (Universal Mobile Telecommunications System) example of cellular telecommunication system comprises such as GSM (global system for mobile communications) or various system based on GSM (as GPRS:.In general, the cell footprint of cellular telecommunication system or base station overlay area may be defined as a certain geographic restrictions zone by one or several base stations (BTS among the GSM, the Node B among the UMTS) service.The base station is by aerial or radio interface service travelling carriage or similar terminal equipment (UE among the MS among the GSM, subscriber equipment, the UMTS).The scale difference of sub-district is very big, and this depends on the type of environment.For example, minimum at present cell diameter has only tens meters, and maximum cell diameter can be thousands of rice.The shape of sub-district is also different because of the sub-district.The bigger service area of the also combinable formation in some sub-districts.
Each sub-district all can be subjected to the control of suitable control device.For example in the WCDMA wireless access network, the sub-district is by being connected to wireless network controller (RNC) and served by the Node B of this controller control.In the gsm wireless net, the sub-district is by being connected to base station controller (BSC) and served by the BTS of this controller control.BSC/RNC is connected to mobile switching centre (MSC) and is subjected to the control at this center, and BSC/RNC also can be connected to Serving GPRS Support Node (SGSN) and by its control.The MSC interconnection of mobile network, and have one or more gateway MSC (GMSC), this mobile network is connected to public switched telephone network (PSTN) and other telecommunications network.SGSN is connected to Gateway GPRS Support Node (GGSN), and GGSN is connected to internet and other packet switching network with mobile network.Some sub-districts cover a bigger zone, and constitute the area of coverage of cellular telecommunication network together.
Travelling carriage in the sub-district of telecommunication system is correspondingly by base station services, and is subjected to the control of base station controller.MS/UE can while and two or more base station communications.These two or more base stations can be connected to same controller or different controller.Therefore, although UE at that time may be only by a base station and controller service, it also can be connected to several base stations and/or controller simultaneously.This situation for example can occur in, when the overlapping or travelling carriage of the area of coverage of sub-district is in so-called inter-cell soft handoff pattern.One of them controller can serve as service (master) controller, and another controller can serve as pilot controller.
Cellular telecommunication system can be divided into so-called core net and Access Network side.This layout can make base station and correlation control unit belong to Access Network, thereby the cell-level feature of system is provided.Then core net provides the network level service, as Access Network being connected to the other parts of telecommunication system.Between Access Network and core net, provide suitable interface, as so-called Iu interface.
Cellular network apparatus also can be applicable in positioning mobile station and user's thereof the environment.Particularly, because cellular telecommunication system is known current sub-district related with travelling carriage or service area, sub-district or similar geographic restrictions area of radio coverage and correlation control unit are convenient to telecommunication system and are generated the estimation of rough location information at least that relates to the travelling carriage current location.For example can obtain the information of the associated sub-district of relevant travelling carriage by paging, location area updating, cell update, URA renewal or Routing Area Update.The positional information that covers based on the sub-district can be designated as the cell identity, service area identity of used sub-district or the geographical coordinate of the position relevant with Serving cell.This positional information can comprise that QoS (service quality) estimates (for example, the precision about reaching).When geographical coordinate was used as positional information, the position of estimated travelling carriage can be the fixedly geographical position in the Serving cell (for example position of serving node B), the geographic center of the Serving cell area of coverage or other certain fixed position in the cell footprint.The geographical position also can obtain as signal two-way time (RTT) by information and some other available information of combination about specific fixedly geographical position, sub-district.
Therefore, infer in sub-district or geographic service area that the given time travelling carriage may be located it is possible.Be interviewed or also can obtain this information during the area of coverage of " other places " network when travelling carriage is positioned at.Can make visited network the position of travelling carriage can be sent back home network, for example in order to support positioning service or to be used for the routing and charging purpose.
Therefore location-based service can cover or service area based on the sub-district.Propose more specifically that according to one cellular communication system can provide location of mobile station and the time mark of knowing recently.The location-based service feature can be provided by separate network unit or the server from the system controller receiving position information.For example, in GSM, this information can obtain from the Visitor Location Register (VLR) of the MSC that is interviewed or from the attaching position register (HLR) of home network.This proposal will be given the precision of a sub-district, location, that is, it will indicate travelling carriage in the area of coverage of (at least once existing) certain sub-district.
Service area such as sub-district and/or base station overlay area is typically discerned by suitable identifier, and each service area just can be distinguished by system like this.Usually can notify travelling carriage and controller current identifier.It should be understood that and indicate the described identifier of current area and/or base station to represent, for example sub-district ID or location area identity (LAI) or service area identity (SAI) with various terms.Following technical specification uses term ' service area identity ' to represent that all relate to the unit by telecommunication system, as sub-district or area group or base station or base station group, these identifiers in the zone of service.
Some Service Area Identifier symbol is related with travelling carriage simultaneously to be possible.This can for example occur in, thereby the so-called soft changing state that cell footprint is overlapping or travelling carriage is in the minizone is during with an above base station communication.Therefore the location-based service based on the information of service area can receive an above identifier.The inventor has found that this will cause undefined behavior in some cases, i.e. this location-based service possibly can't provide the precise position information that provides as under the situation that only receives an identifier.In addition, location-based service may can't be handled the location information data based on two (or a plurality of) different identification symbols at all.
Summary of the invention
The objective of the invention is to solve one or several above-mentioned problem.
According to an aspect of the present invention, provide a kind of method that the positional information relevant with travelling carriage is provided in telecommunication system, described telecommunication system comprises a plurality of service areas, and each described service area is all accorded with by Service Area Identifier and discerning, and described method comprises step:
The Service Area Identifier symbol that request is relevant with the travelling carriage of described telecommunication system;
According to the pre-defined rule that is used to select the Service Area Identifier symbol, from a plurality of possibility Service Area Identifier symbols relevant, select a Service Area Identifier relevant to accord with described travelling carriage with travelling carriage;

Embodiment
At first with reference to figure 1, three base stations provide omnidirectional's area of radio coverage 1,2 and 3 of cellular telecommunication network in Fig. 1.Although the exemplary telecommunications net of illustrating in detail and describing uses the term of WCDMA (Wideband Code Division Multiple Access (WCDMA)), UMTS (Universal Mobile Telecommunications System) and public land mobile net (PLMN), but the solution that it should be understood that proposition can be used for providing communicating by letter and any cellular system of certain location information service between travelling carriage and the base station.In addition, a sub-district can comprise an above base station, and base station apparatus may provide an above sub-district.
In Fig. 1, each area of radio coverage 1,2 and 3 is served by base station (Node B or BTS) 4,5 and 6 separately.Particularly, each base station arranges to be used for to travelling carriage (MS, UE) 7 transmission signals and from its received signal.Equally, travelling carriage 7 also can be to separately base station transmit signals and from its received signal.Travelling carriage 7 is then realized this function with communicating by letter of base station.Although for the purpose of clear, only show a travelling carriage, a plurality of travelling carriages and each base station communication typically will be arranged at Fig. 1.
Each base station all is connected to network controller 10, and in exemplary PLMN system, controller 10 is the radio network controller (RNC) of UMTS grounding wireless access network (UTRAN).Should be pointed out that an above controller is provided in network usually.Radio network controller 10 is connected to suitable core network entity such as MSC and SGSN 40,41 by means of suitable interface arrangement (see figure 4) usually.Radio network controller can be connected to GSM MSC A-interface by A-interface/Iu interface interworking unit (IWU).
Travelling carriage 7 can move to another cell footprint from a cell footprint.When travelling carriage freely when a position (base station overlay area or cell footprint) moves to another position (to another area of coverage) and still be in the area of coverage, therefore the position of travelling carriage 7 can change at any time.
Each of sub-district 1 to 3 all is shown as among Fig. 1 provides two radio to cover circle 8 and 9.The area of coverage that the what is called of the interior circle 8 signal sub-districts of each sub-district is dwindled.Cylindrical 9 is then illustrated the area of coverage of what is called expansion of sub-district.Zone between circle 8 and the circle 9 is known as soft handover area 11.As long as travelling carriage 7 is within soft handover area 11, it all can receive an above sub-district, and can carry out signaling with an above signal branch from corresponding base station and communicate by letter.The result of grand diversity makes that travelling carriage can be simultaneously relevant with an above cell identifier.According to estimates, the travelling carriage percentage of time that is positioned at soft handover area is approximately 30% to 40%.
Fig. 2 shows the area of radio coverage 16,17 and 18 of three beam shapes.Each disclosed area of radio coverage all is made up of the orientation of base station 14 and 15 or the sector that fan antenna provided.Should be pointed out that fan-shaped base station also can provide omnidirectional's area of coverage.This can for example pass through 3 120 ° of directional antennas realizes, thereby 360 ° of area of radio coverage are provided, or passes through 4 90 ° of directional antennas etc., or covers arbitrary combination realization of beamwidth by different radio.As shown in the figure, base station 14 is provided at switch area 11 ' and locates overlapping two radio coverage sectors 16 and 18.This switch area between the sector 16 and 18 can be called " softer " switch area.Show in the soft handover area 11 of travelling carriage 7 between the circle 8 and 9 of above-mentioned sector 16 and 17 among the figure.
Fig. 1 also shows location-based service (LCS) node 12 that location-based service is provided for different application or client computer 20.In general, the LCS node may be defined as a kind of entity, and this entity can provide the information that relates to the travelling carriage geographical position, especially relates to the information in the geographical position that defines with respect to the position of the base station of mobile telecommunications network based on travelling carriage.In the embodiment of Fig. 1 and 4, node 12 is included in the GMLC (GMLC) that the core net side of telecommunication system provides.
Fig. 3 has illustrated in detail according to the function diagram of the location server of ETSI (ETSI) technical specification " location-based service " (3GPP TS23.171 and GSM 03.71).
LCS server is understood the specific (special) requirements and the characteristic of LCS client computer 20 usually by the pre-reduced unitized table of LCS client computer.The specific LCS relevant limit relevant with each target MS also may be stated in the pre-reduced unitized table name and address of sender enclosed of target MS.After specification in will discuss, the location-based service feature can allow at any time to determine the position of target MS.
Positional information can be used for some other purposes and just is not used for call treatment (route, charging, resource allocation etc.), below is the example of possible client computer.Client computer will the information relevant with the position---for example about the travelling carriage in the specific geographical area such as the information broadcast in weather, traffic, hotel, restaurant etc.Client recording anonymous location information (promptly not having any MS identifier)---for example be used for traffic engineering and statistics purpose.Client computer strengthen or support that any supplementary service, IN (intelligent network) are professional, bearer service or by the teleservice of target MS consumer premise.These only are examples, but other any suitable client computer use location service node all.When sending urgent call, can use travelling carriage this service to determine the position of travelling carriage certainly.Also have some other possible commerce and non-commercial applications, the positional information that is provided by location-based service (LCS) can be provided for they.These possible application (for example comprise different local advertisings and information distribution scheme, only send information at those mobile subscribers that are currently located in a certain zone), the WWW-page relevant (for example timetable, local restaurant, shop or hotel directory, map local advertising etc.) that use for the user of mobile data treatment facility with the area, and by hope receives that this information and mandate obtain this information anyone follows the tracks of the mobile subscriber.Needing the application of the real-time position information that travelling carriage moves is that network is spendable travelling carriage moving projection feature in the dynamic network resource allocation for example.Also there be using and using of other various possible positional informations, can use this positional information.
The position deterministic process should utilize some information sources to determine the position.Propagation and deployment conditions can limit the quantity or the quality of measurement, and perhaps additional measurement also is possible.Some travelling carriages also can have additional (independence) position information source of aforementioned type.LCS should utilize suitable limited or additional information to the business of being asked.Therefore by utilizing all places to measure and/or determining that the result of technology can improve positioning accuracy.A kind of possibility is that the definition travelling carriage sends the propagation time (or propagation time difference) of radio signal to the base station.According to another kind of possibility, the location is based on the measurement that is realized by at least three different base stations that cover the current zone of living in of travelling carriage.In addition, from reliable external source, for example can obtain the geographical position from well-known satellite-based GPS (global positioning system).Can obtain more accurate positional information by differential GPS.Except GPS, can provide any other similar system of reliable position information all to can be applicable to this.The positional information ratio that also has some other suggestions to provide is more accurate based on the information of cell footprint.Also may have the system that some diverse location service accuracy classes are provided, the method that wherein is used for determining the position depends on the precision of being asked.Desired precision can be by for example, and so-called service quality (QoS) parameter that is included in the location information request is indicated.
Location-based service, for example the GMLC node 12 of Fig. 4 is configured to from the response of Access Network request position information conduct to the location information request (LCS request) of client computer 20.According to preferred embodiment, GMLC 12 then sends to network controller 10 in the Access Network by gateway apparatus (MSC 40 and/or SGSN 41) and by interface 13 with this request.The service controller of Access Network is determined the precision of positional information then, selects suitable localization method, and provides suitable positional information to GMLC 12.
According to another embodiment, location-based service, for example the GLMC node 12 of Fig. 4 is determined required precision according to the LCS request that receives, and is selected suitable localization method.Below the embodiment of contrast Fig. 1 and Fig. 4 discussion will consider the situation of selection based on the positional information of cell footprint.
When GMLC 12 request position information, it is the required precision of definition in service quality (QoS) parameter for example.If precision is defined as meeting cell footprint, the RNC 12 of core net device 40 and/or 41 request UTRAN sides provides the Service Area Identifier symbol of target MS.According to embodiment, the Service Area Identifier symbol that turns back to GMLC 12 is comprised the cell identifier (cell_ID) of the sub-district of current service travelling carriage, or the identifier or the parameter that derive from this cell identifier.
According to embodiment, the Service Area Identifier symbol that turns back to GMLC 12 is included in the estimation geographical position of the travelling carriage of indicating in the geographical coordinate, and comprises the information that reaches precision (level) about estimating.
According to embodiment, if thereby travelling carriage is positioned at the area of coverage of some sub-districts when relevant with some identifiers, and network controller 10 is selected to be sent to a conduct in some identifiers of core net to this request responding from Access Network side (UTRAN Fig. 4).Be sent to the cell identifier of the preferred selected sub-district of identifier of GMLC 12, but also can be based on any other parameter of the selection of service area.Network controller 10 makes a choice based on the following pre-defined rule that will discuss or one group of rule.Fig. 5 shows a possible flow process of decision process.
The selection of Service Area Identifier symbol is preferably carried out by controller 10.Yet any network element of other in the network comprises the base station of travelling carriage 7 and Access Network also can being configured to make a choice based on pre-defined rule.
According to a kind of possibility, the selection of Service Area Identifier symbol is based in order to determine the signal power between travelling carriage and the receivable base station of travelling carriage or the measurement of intensity.After the measurement, the Service Area Identifier symbol that preferred selection is relevant with peak signal.
If the selection of Service Area Identifier symbol is based on signal power or intensity, then the position is definite can be based on the use of reference signal.This specific embodiment can be based on or some in the following principle:
-when soft changing state or existence comprise the efficient set signal of some signal branch, in case selected branch belongs to that this efficient set is just selected a bars branch and used as benchmark branch.If benchmark branch is deleted or replacement, then can determine cell identifier based on inferior good reference signal (branch).
-in case be not included in basic common pilots channel (CPICH is in WCDMA) in this efficient set and become and be better than belonging to the basic CPICH of this efficient set, just change (renewal) selected cell identifier.
-in case becoming, basic CPICH is better than previous best basic CPICH, also change selected cell identifier.
-in a single day basic CPICH becomes and is better than also changing selected cell identifier based on the signal level of other effective branch or the absolute thresholding of determining in addition.
-in case basic CPICH becomes inferior to absolute thresholding, just change selected cell identifier.
-in case becoming, basic Common Control Physical Channel (CCPCH) is better than previous best basic CCPCH, just change selected cell identifier.
In case the SIR of-time slot (signal interference ratio) value becomes inferior to the absolute door limit value, just changes selected cell identifier.
In case the signal code power of-time slot disturbs (ISCP) value just to change selected cell identifier inferior to absolute thresholding.
In case the ISCP value of-time slot is better than a certain predetermined thresholding, just changes selected cell identifier.
-in general, in the cell identifier deterministic process, can utilize LCS_MARGIN.LCS_MARGIN can be based on power level (side-play amount) or any similar approach of triggered time, stand-by period, signal.LCS_MARGIN can be used for stoping unnecessary cell identifier to upgrade to avoid the impair system performance.LCS_MARGIN can be applicable to forbid or allows cell identifier to upgrade trigger.
Another program is other any parameter of determining signal to noise ratio (snr) or defining the quality of the signal branch that receives.Equally, preferred but and nonessential should the selection based on best quality signal branch.Also is possible with this selection based on further feature or parameter to signal branch measurement that is received or the signal that detects.
Also can determine base station nearest in the several base stations, and with the basis of this information as selection.For example the radio signal that sends based on travelling carriage time of arriving the base station can be determined the distance between travelling carriage and the base station, and vice versa.Another example is so-called round trip cycle (RTT) method.Signal is relevant with the propagation distance that following formula provides in the propagation time of arbitrary base station:
R＝cT， 〔1〕
Wherein
The R=travelling carriage is to base station distance (scope)
The C=light velocity, and
The propagation time of T=radio signal.
Range information also can in order to determine other any such feature of signal strength signal intensity, signal to noise ratio or received signal, can be determined the distance between cell site and the receiving station thus based on the measurement of carrying out in receiving station.
Should point out that the measurement of radio signal characteristics can realize at up link and/or down link, can be at the base station end or at mobile you or by the two common realization.If travelling carriage is used for measuring-signal, it can use the control channel of wireless network for example measurement result is sent to suitable network element.Calculate and determine and to realize that at website (base station or travelling carriage) or in the suitable network element that can use all desired datas for example network controller 10 based on necessity of the data of various collections/definition.
As long as select to judge the measurement that is based on the one or several features of the signal between travelling carriage and the corresponding base station, will occur changing rapidly such as the measurement features of signal strength signal intensity or quality.Therefore definition determines that the mean value of window or interval and definite feature is better.Then the corresponding mean value of described mean value and other signal branch is made comparisons, and relatively make a choice based on this.
According to a kind of possibility, selected Service Area Identifier symbol is the Service Area Identifier symbol that generates when travelling carriage is for the last time by successful paging during process is set up in connection.This can be applicable to the calling that travelling carriage is a receiving end usually.The Service Area Identifier symbol that selected Service Area Identifier symbol also generates during process is set up in the connection between travelling carriage and the serving BS.This can be applicable to the connection that travelling carriage starts usually.
According to a kind of possibility, selected Service Area Identifier symbol is a travelling carriage the oldest associated Service Area Identifier symbol.According to another kind of possibility, selected Service Area Identifier symbol is the associated up-to-date Service Area Identifier symbol of travelling carriage.Up-to-date Service Area Identifier symbol may be the identifier of the sub-district that switches to from previous sub-district recently of travelling carriage, or travelling carriage has begun to receive but the identifier of nearest " newly " sub-district of not switching to as yet.Selected Service Area Identifier symbol also may be the Service Area Identifier symbol that the sub-district of effective connection is provided for travelling carriage when network controller receives new LCS request.
According to a kind of possibility, from a plurality of possible service areas, select sub-district or other service area based on preferred or priority order.
As shown in Figure 5, it is possible using one or more rule in selection course.When using one or more rule, controller is provided with the rule of the relation between the selected rule of definition in addition.For example, the one or more parameter-definition threshold levels for this rule should be possible.For example, before the rule of selecting based on the distance between travelling carriage and the base station, this distance must be shorter than predetermined threshold distance.According to another example, unless use rule based on signal strength measurement just measured one or more intensity surpass predetermined threshold value.The maximum or the smallest size of a possible threshold parameter definable sub-district or another service area.In this linguistic context, also can use sighting distance (LoS) condition.
According to a kind of possibility, according to preferred sequence, promptly priority order is provided with rule.In this scheme, controller follow the principles selection algorithm or tree, until having selected the Service Area Identifier symbol based on one in the follow-up rule, maybe this request has been submitted to the possible selective rule of the last item.If even the possible rule of the last item still can't provide identifier,, and provide subscriber computer 20 suitable message then preferably with this notice GMLC 12.
Should be pointed out that Fig. 5 only discloses an example of these regular predefined procedures, the order of these rules and/or quantity may be different therewith.In addition, the relation between the rule also can change about the time (adopting Different Rule on night and daytime) or about the loading condition of controller or network.According to a kind of possibility, can be used for selecting the rule of Service Area Identifier symbol to select pre-defined rule with the response scheduled event.In other words, employed rule depends on such as the identity of the location service node of type, the request position information of request and the conditions such as identity of client computer.
Telecommunication system can be supported so-called intermode environmental applications, and the foregoing description also can be applicable to this linguistic context.The intermode environmental applications comprises such as supporting that localization service area (SoLSA), mobile network higher-order logic customization application program (CAMEL) etc. are professional.Utilization such as the existing kit of SIM application toolkit (SAT) or CAMEL can be realized based on the LCS of cell identifier or general LCS.The application that provides in the CAMEL service environment (CSE) based on the sub-district is provided CAMEL, and this can be used for SoLSA.CSE for example comprises, revises and forbids conversation based on the charging of cell information.Yet, because network can realize by using some business platforms, therefore this only with CAMEL as a case description.
Present embodiment also can be applicable to or uses in conjunction with the advanced location feature of other of cellular system.These features comprise localization service area (LSA) priority, the access that is only limited to LSA, exclusive access, preferred access etc.The intermode environment can comprise the different cellular systems that have the multi-layer honeycomb structure, and as GSM, WCDMA etc., described multi-layer honeycomb structure comprises macrocell, Microcell, picocell and home cell.To describe some examples of these features below in detail.
The LSA priority is the priority of user's LSA.If the user then judges that based on the LSA priority which is a current LSA among these LSA in that some effective LSA are arranged sometime.In Fig. 6, LSA A is than LSA B priority height.The priority of sub-district can only compare between suitable sub-district.The feature of LSA priority is that a certain sub-district of operator's definable is selected prior to another sub-district.For example, if so-called umbrella shape sub-district is selected prior to Microcell, so because the very big remaining resource of frequency reuse distances of umbrella shape sub-district will be seldom.
In the access that is only limited to LSA, only allow the user when it is positioned at the LSA of reservation, just to insert PLMN.When the user when its LSA is outside, can not receive or make any calling.In other words, cell identifier can be used for blocking and/or allows travelling carriage to use in the sub-district.Exclusive access sub-district then is anyone sub-district that all can't use the user of the LSA under those belong to this sub-district.
Preferred access sub-district is the sub-district that belongs to preferred specific LSA, is the user who belongs to this LSA and gives some predetermined priority.This sub-district is to the only limited access right of non-LSA user.
For during the effective model of travelling carriage, supporting exclusive access, be only limited to the access of LSA and preferably access that preferably the similar units at RNC, BSC or Access Network obtains this LSA information.
The embodiment that selected cell identifier uses together with the power control mechanism of radio telecommunications system below will be discussed.But cell identifier is determined the joint Power controlling mechanism, and the possibility of result of cell identifier request or power control instruction (power adjustment) meeting phase mutual interference like this is although they can be in the use in service of further feature.For example, if determined cell identifier, so effectively other signal branch that connects relevant powers up instruction (being used to increase power) and may be left in the basket.And the instruction that powers up of selected sub-district may be just effective when selected sub-district is optimal candidate.On the other hand, cut-offing instruction only to non-candidate branch but not optimal candidate (preferred cell identifier) effectively.The different distortion that should be appreciated that power control and the definite combination of cell identifier is possible.Should select them to improve systematic function based on system load, interference, radio environment, LCS request etc.
Cell identifier also can be used in combination with a station selection diversity power control (SSDT).A selection diversity delivering power control (SSDT) of standing is the power control forms that can use down link when travelling carriage is in soft handover.According to the principle of SSDT, the best cell in the Dynamic Selection efficient set is as a dispatching station field.In this case, the cell identifier method with determine harmonious based on the cell identifier of SSDT criterion.
In addition, this embodiment can get in touch idle period downlink (IPDL) use.In IPDL, each base station stops to transmit predetermined short time period in turn fully, and this mode provides effective measuring period for all terminals in its area of coverage.This can realize by the strong interferers of decay serving BS, to improve the signal interference ratio of measuring (SIR).Embodiments of the invention have also been considered the inactive cycle of IPDL mechanism.This can be for example by ignoring the inactive cycle of reference signal power, making cell identifier renewal frequency and the period frequency coupling of should stopping using (if for example inactive cycle is not frequent especially generation) wait and realize.
Fig. 7 shows under different WCDMA radio resource control (RRC) states, and the difference of portable terminal may state in third generation environment.Embodiments of the invention can be supported the location based on cell identifier under any state shown in Figure 6, comprise that URA_PCH, Cell_PCH, Cell_DCH, Cell_FACH, sub-district are reselected, system's inter mode and idle pulley.
If travelling carriage is not in effective status, promptly between travelling carriage and at least one sub-district, do not have and be connected, then possibly can't obtain the Service Area Identifier symbol.For example in UMTS, only between travelling carriage and at least one base station, exist radio resource control (RRC) just can provide sub-district ID when being connected.Therefore, Service Area Identifier symbol can't to be turned back to core net be possible to network controller.If travelling carriage is in the pattern that cell identifier (or covering) can't be provided, can force the state that this travelling carriage enters provides cell identifier so.For example, in the URA_PCH state, possibly can't obtain cell identifier.Can force MS to enter Cell_FACH, like this as long as the LCS node needs just can obtain cell identifier with the definition cell identifier.In addition, network can stop MS to enter the URA update mode so that receive cell update when MS selects new sub-district.
If MS be in idle pulley and also need paging it, can trigger by the paging that is used for the LCS purpose of starting of core net or UTRAN Access Network so.Except the paging method of routine, below possible enhancement measures can be applicable to the paging purpose:
-can be used for determining about the nearest available information (LCS auxiliary data) in the geographical position of MS should at first paged zone.
The speed of-MS and direction (or other any mobility parameter) can be used for determining paging zone and paging repetition period.
-under the high-speed mobile situation, suppose that one group of suitable nearest cell identifier (or LCS auxiliary data) can be used for paging zone and determines.
-also can be used for optimization position district, repetition period etc. based on the LCS auxiliary data of sub-district.
Should be appreciated that the LCS auxiliary data can be used for optimizing any one paging and process is upgraded in the position.
Cell identifier is determined and can be comprised effectively and idle pulley based on Different L SA pattern.A kind of possibility is that first priority belongs to a predetermined LSA application (for example, SoLSA or any other LSA) when determining cell identifier.For making travelling carriage (MS) trouble free service in network, it must obtain the idle pulley support.This means that MS may need a kind of feature that can make it reselect correct sub-district when preemption is in the sub-district of idle pulley.The term preemption is meant that MS is in idle pulley in the sub-district.MS should attempt reselecting the sub-district of the LSA that belongs to the user all the time.If can obtain several sub-districts, then should reselect sub-district with highest priority.
MS (for example when travelling carriage is switched on) when selecting the sub-district can use conventional cellular system method.This is that for example the signal power parameter by receivable each sub-district of measurements and calculations travelling carriage realizes, selects to have the sub-district of optimum power value afterwards.Reselecting of sub-district can be finished by calculating additional parameter.At first having highest priority secondly has the sub-district of high additional parameter and will be reselected.
In non-LSA sub-district, the signal power CALCULATION OF PARAMETERS for example can comprise, threshold parameter RXLEV_ACCESS_MIN, but also may use LCS_RXLEV_ACCESS_MIN to the LCS sub-district.May need independent parameter to guarantee the LCS and the quality of connection that normally is connected in the LSA sub-district.Another the new thresholding or the absolute rating that can be broadcast to MS are LSA_CAMPING_MARGIN.If than the parameter value of low priority sub-district (or common sub-district) the corresponding parameter that is higher than the higher-priority sub-district that becomes is limit L SA_CAMPING_MARGIN, MS will preempt than the low priority sub-district so, even LSA_RXLEV_ACCESS_MIN still is positive.
LSA_RXLEV_ACCESS_MIN can be used for guaranteeing that MS supports the LSA sub-district, and LSA_CAMPING_MARGIN can be used for guaranteeing that network spectrum efficient can not become low.It also can be used for making the stand-by time of MS longer.
New sub-district is reselected parameter and also can be broadcasted in system information.These parameters will be with other radio parameter from O﹠amp; M is sent to UTRAN/BSS.
When travelling carriage was in effective model, controller unit (for example RNC of BSC) needed user LSA information to support the LSA sub-district.This information can copy to controller unit between transfer period during the call setup and/or between RNC/BSC.RRC message and information unit can designatedly be used for information and transmit.The LSA information unit should be discerned the priority and the local access pointer of preferable cell, these sub-districts.
For reducing the amount of information that transmits, described information can only comprise the information of LSA, for example, if:
-Serving cell is the member of this LSA; Or
-one of them adjacent area is the member of this LSA; Or
It is essential and belong to the MS abridged table of Set For Current that-this LSA is set to effective model support (at MS), and RNC/BSS supports this LSA.
Information transmits and can occur in the call setup any time of RRC connection foundation back.
During the process (in the LCS that covers based on the sub-district) that cell identifier is determined and by the effective model support, for example belong to sub-district for the cell identifier set of user's LSA purpose when call setup and/or switch when realizing supported.Associated user's LSA information can for example obtain at BSC, RNC etc. in the related network unit.Associated user's LSA information will be sent to described unit at call setup with between outside transfer period.
In certain embodiments, preferably hide the radio aspect of telecommunication system from core net.For example in third generation system, cell identifier should be mapped to the service area parameter that transmits by the Iu interface between UTRAN network and core net.As mentioned above, service area can comprise one or several sub-districts.This mapping can be finished at RNC/BSC, network management system (NMS comprises network management unit NEMU) or by the cooperation of various Access Networks unit.For determining that the sub-district covers estimation and it is mapped to the service area parameter, can be together with relevant cell identifier utilization such as the optimal criteria signal, parameter and the antenna beam directioin parameter of the two-way time (RTT) between base station, travelling carriage, location measurement unit (LMU) and the datum node positioning unit.In this case, the controlled area can be used by base station BS periodically or the reference signal two-way time (RTT) of measuring on request.
Measure based on described RTT, can obtain more accurate location estimation by utilizing so-called two-way time poor (RTTD) principle.Particularly, RNC or other network element (or mobile device) that relates to positioning calculation process can utilize the two-way time of base station measurement poor (RTTD), geometrical time difference (GTD) and true/relative time poor (RTD).The RTT that is finished by respective base station by utilization/comparison measures and can calculate RTTD at for example RNC.On the other hand, GTD can calculate by the position that utilizes RTT measurement and respective base station.RTD is the relative synchronization discrepancy between two base stations in network, can be measured by LMU (location measurement unit).In addition, also can calculate RTD by utilizing the network fundamental measurement.For example in UMTS, connect frame number (CFN)-system frame number (SFN) observed time difference, or the SFN-SFN observed time difference can be applicable to described purpose.The time difference that DRTT comes and goes from different base stations based on signal.If mobile station MS and base station BS
1With with BS
2Between difference be Δ t, and between MS and this two BS sighting distance (LOS) is arranged, MS can be positioned on the hyperbola, that is: so
d1-d2＝cΔt (2)
Wherein
D1 is from MS to BS
1Distance,
D2 is from MS to BS
2Distance, and
C is the light velocity.
Utilize three different base stations can measure DRTT, and MS is positioned at these hyp intersection points.
By utilizing RTTD, GTD and RTD simultaneously, can come positioning mobile station by two hyp intersection points and two GTD of obtaining by three base stations.By utilizing more GTD can make possible lane place littler.In system, can determine corresponding RRT by so-called timing advance (TA) method based on TDMA such as GSM.Therefore, also can in based on the system of TDMA, use the notion of DRTT method described above by using different timing leading (DTA).
BS can measure the timing biasing between the beginning (first active path) of the beginning of down link DPCH frame and corresponding up link UPCH frame.The precision of described measurement is preferably the subcode chip level.MS can provide itself and the reception of controller and the additional period between the transmission to setover to calculate definite RTT.
Perhaps, can determine the scope of sub-district by using the reference signal power budget.For example can obtain based on described reference signal power budget, base station transmitting power, isotropism path loss, to the covering thresholding at the coverage area boundary place of given position probability, be used for the cell range that indoor or outdoors covers.
In some cellular systems such as CDMA, cell range can change at any time, and promptly cell sizes can increase according to the condition such as the travelling carriage quantity that is connected to the sub-district or dwindle.Cell range (radius) can be based on for example, and well-known Okumura-Hata or other any suitable method are estimated.Final radius of society also can define based on following principle:
Wherein Pr is a received power, Pt is that the transmitting power (equivalent isotropically radiated power EIRP) of base station adds receiver gain, Pl is a path loss, Pl (r0) is that near known reference distance r0 (is 1km for bigger urban district mobile system for example, for Microcell is 100m, and be 1m for picocell), r is the distance apart from the base station.Last depends on the error correction that causes because of received power deviation, MS mobility etc.
Controller or LCS node will use based on the cell range (radius) of reference signal link budget with cell identifier to be estimated to estimate the covering of service area.
Yet according to another kind of scheme, but the observed time difference of controller using system frame number (SFN-SFN) and connection frame number and system frame number (CFN-SFN) is determined the more exact position of cell range or MS.
Under above-mentioned any situation, comprise that interaction between the neighbor cell area of coverage of error margin can be used for determining the more exact position of travelling carriage.
If the observed time difference of SFS and CFN is used to improve location estimation, the position of MS should be positioned at neighboring radio and covers hyp interaction zone so.Except nearest cell identifier (LCS estimation), can utilize MS speed and direction that cell identifier is mapped to respective coverage areas and/or service area.In addition, can utilize auxiliary data (for example LCS data, transmitting power control data etc.) in radio net layout data, BS/MS reference power (emission with receive), sub-district and/or station layout, the RNC/BSC/NMS that cell identifier is mapped to the sub-district covers or service area.Described mapping may be finished at the Access Network place, so the LCS node may have position coordinates.In other words, it is possible providing the Service Area Identifier symbol of being made up of the lane place coordinate to core network element.
According to a kind of possibility, the power level of reception is compared with power budget, and more accurate location of mobile station information can be provided thus.Also combinable by the calculating that two or more unit carry out.
Can use any combination of said method and measurement parameter in an embodiment of the present invention.Also can define the coordinate of cell footprint or service area according to circle, ellipse, polygon etc.
Can satisfy the requirement of most of LCS business based on the location of sub-district covering (Cell-ID).The precision of this method may not wait from several meters to several kilometers, and this depends on the cell structure and the radio environment of system.These services can comprise location service class, for example:
In-dwelling house or the office, wherein the sub-district is the sub-district that is provided by indoor base station;
In-dwelling house or the office and adjacent area, the service area (LSA) that wherein localizes is outdoor broadened.Outdoor adjacent area can be included in the local service area that is used for indoor cell;
